Article 10.X.10.

Importation of aquatic animals, excluding gametes and fertilised eggs, for aquaculture from a country, zone or compartment not declared free from infection with [pathogen X]

When importing, for aquaculture, aquatic animals, excluding gametes and fertilised eggs, of a species referred to in Article 10.X.2. from a country, zone or compartment not declared free from infection with [pathogen X], the Competent Authority of the importing country should assess the risk in accordance with Chapter 2.1. and consider ~~applying~~ the risk mitigation measures in ~~either~~ pointss 1 and~~or~~and 2 below.~~:~~.

1)	If the intention is to grow out and harvest the imported aquatic animals, consider applying the following:

~~Either~~

a) 	the direct delivery to and lifelong holding of the imported aquatic animals in a quarantine facility; and 

b)	before leaving quarantine (either in the original facility or following biosecure transport to another quarantine facility) the aquatic animals are killed and processed into one or more of the aquatic animal products referred to in Article 10.X.3. or other products authorised by the Competent Authority; and 

c) 	the treatment of all transport water, equipment, effluent and waste materials to inactivate [pathogen X] in accordance with Chapters 4.4., 4.8. and 5.5.

~~Or~~

~~d)	apply the requirements of Chapter 4.Z.~~

OR

2) 	If the intention is to establish a new stock for aquaculture, consider applying the following:

~~Either~~

a) 	In the exporting country:

i)	identify potential source populations and evaluate their aquatic animal health records;

ii)	test source populations in accordance with Chapter 1.4. and select a founder population (F-0) of aquatic animals with a high health status for infection with [pathogen X].

b)	in the importing country:

i)	import the F-0 population into a quarantine facility;

ii)	test the F-0 population for [pathogen X] in accordance with Chapter 1.4. to determine their suitability as broodstock;

iii)	produce a first generation (F-1) population in quarantine;

iv)	culture the F-1 population in quarantine for a duration sufficient for, and under conditions that are conducive to, the clinical expression of infection with [pathogen X], and sample and test for [pathogen X] in accordance with Chapter 1.4. of the Aquatic Code and Chapter 2.3.6. of the Aquatic Manual;

v)	if [pathogen X] is not detected in the F-1 population, it may be defined as free from infection with [pathogen X] and may be released from quarantine;

vi)	if [pathogen X] is detected in the F-1 population, those animals should not be released from *quarantine* and should be killed and disposed of in a biosecure manner in accordance with Chapter 4.8.
